Which seems a bit far afield from reality to me. Yes, there are lots
of folks with IPv6 connectivity and v4-only recursive DNS servers. I
don't think ISPs will have problems setting aside a handful of IPv4
addresses for authoritative DNS infrastructure to work around this
until v6 transport in recursive DNS servers is common enough.
Dave,
I think part of the point of this is to discover gotchas with our
current infrastructure. For example, while diagnosing why I couldn't
get onlyv6.com to resolve on one of my name servers but the others
worked fine, I discovered that PowerDNS Recursor won't use an IPv6
address for outgoing queries unless you actually give it:
query-local-address6=
One of my name servers had it, the other didn't, hence I was getting
failures on one and success on the other. Its little config issues like
that that can crop up weeks/months/years later and make life difficult.
Now that I'm a Xen shop, I design domUs to last years at a time rather
then rebuilding them constantly. Being able to shunt stable and
reliable domU hosts to new dom0 machines when they come up is a great
thing, and makes my life alot easier. :)
